TCA Cross
Medical Dermatology & Scarring Treatments: Chemical Reconstruction of Skin Scars
At Sun and Skin Medical Centre in Mt. Eliza, Victoria, we specialize in Chemical Reconstruction of Skin Scars (CROSS), an advanced technique designed to improve the appearance of acne scars and other types of depressed scars. This innovative treatment uses highly targeted chemical peels to stimulate collagen production, smooth out uneven textures, and restore a more even complexion.
What Is Chemical Reconstruction of Skin Scars (CROSS)?
Chemical Reconstruction of Skin Scars (CROSS) is a dermatological procedure that involves applying a high-concentration chemical solution, such as trichloroacetic acid (TCA), directly to scar tissue. This targeted approach promotes controlled chemical injury to the skin, stimulating collagen remodeling and improving the depth, texture, and overall appearance of scars.

Key Features of the CROSS Technique:
- Focuses on individual scars rather than large areas of skin.
- Stimulates natural healing and collagen production.
- Minimally invasive with minimal downtime.
Who Is a Candidate for Chemical Reconstruction of Skin Scars?
The CROSS technique is particularly effective for patients with:
- Atrophic Scars: Shallow, pitted scars caused by acne or other injuries.
- Ice Pick Scars: Deep, narrow scars that are difficult to treat with other methods.
- Boxcar Scars: Wider, U-shaped scars with defined edges.
- Rolling Scars: Depressed scars that cause uneven skin texture.
Patients with active acne or certain skin conditions may need to address those concerns before undergoing the CROSS procedure.
Why Do Scars Form?
Scars develop when the skin’s healing process is disrupted, often due to severe acne, injuries, or surgical procedures. Atrophic scars form when the skin produces insufficient collagen during healing, resulting in depressions or pits in the skin.
How Does Chemical Reconstruction of Skin Scars Work?
The CROSS technique involves precise application of a chemical solution, typically trichloroacetic acid (TCA), to the scarred areas.
The Process:
- Consultation and Assessment
- At Sun and Skin Medical Centre, our specialists will evaluate your scars, skin type, and overall health to determine if CROSS is the best treatment for you.
- Application
- During the procedure, a small amount of TCA is carefully applied to the base of the scar using a fine applicator.
- The solution penetrates the scar tissue, triggering a controlled inflammatory response.
- Healing and Remodeling
- Over the following weeks, the treated skin regenerates, producing new collagen and smoothing out the scar’s appearance.
- Repeat Sessions
- Depending on the severity of your scars, multiple sessions may be recommended to achieve optimal results.
Benefits of Chemical Reconstruction of Skin Scars
CROSS offers several unique advantages:
- Targeted Treatment: Focuses on individual scars for precise results.
- Enhanced Collagen Production: Stimulates the skin’s natural healing process to improve texture and firmness.
- Improved Appearance: Reduces the depth and visibility of scars, creating a smoother complexion.
- Minimally Invasive: Requires no surgery and involves minimal downtime.
- Customizable: Can be combined with other treatments, such as microneedling or laser therapy, for comprehensive scar improvement.
What to Expect After the Procedure
- Immediate Effects: Treated areas may appear white or frosted immediately after the procedure, followed by mild redness or scabbing as the skin heals.
- Healing Time: Most patients can resume normal activities within a few days, with full healing typically occurring in 1–2 weeks.
- Gradual Improvement: Results improve over several weeks as new collagen is produced.
